Klein Tools 59011 – Frequently Asked Questions
1) Do I need to center punch or drill a pilot hole before using the Klein 59011 step bit?
No. The 59011 step drill bit has an anti-skid tip that removes the need for center punching or a pilot hole on most sizes. That is the practical difference on sheet metal work: you can set the tip on the mark and go without the bit walking across the panel.
2) What materials can the Klein 59011 step drill bit cut?
It works in most metals, including steel, brass, aluminum and copper, plus plastic and wood. It is built for thin sections, so it is a sheet metal and enclosure bit rather than something for thick plate or structural stock.
3) What is the difference between a single-fluted and a double-fluted step bit?
The 59011 is single-fluted. A single flute keeps the cutting edge from skidding as it enters thin material and it is far simpler to resharpen when the edges dull, since there is one edge to dress instead of two. Double-fluted bits clear chips from two sides and are usually chosen for faster cutting, but resharpening them accurately takes more work.
4) Can one Klein 59011 bit drill several different hole sizes, or do I need a set?
One bit covers multiple hole sizes. That is the point of a step bit: each step up the cone is a different diameter, so a single 59011 replaces a stack of twist bits when you are punching conduit knockouts and connector holes in thin metal, plastic or wood.
5) What part number do I order for the Klein #11 single-fluted step bit?
Order Klein Tools 59011. The #11 designation and the manufacturer part number are the same figure, so 59011 is what you put on the PO.
6) How do I know which step I am on when drilling with the 59011?
The hole sizes are laser etched into the bit. Unlike ink or stamped-and-painted markings, laser etching does not rub off with use or solvent, so the size callouts stay readable through the life of the bit.
7) Is the Klein 59011 an electrician's bit or a general shop bit?
Klein catalogs the 59011 as an electrical hand tool, and the design matches that work: thin-gauge steel panels, junction boxes, strut and plastic enclosures where you need several connector sizes without swapping bits. It will also cut brass, aluminum, copper and wood, so it carries over to general maintenance work.
